What are the blackhawks up to?

ok. I'm a huge hawks fan, but I just don't get it. bowman managed to move Campbell and his big *** contract, kopecky, and brouwer. that's an estimate of around 10 million dollars, I assume. so, is this all to extend sharp? or are they gonna go after free agents as well? if so who? I was thinking a youngER defenseman with grit. like wisnewski. I just don't see how they don't sign a defenseman after losing Campbell. is it probable that they would go after belanger or Dubinski too? I would think that the rangers would need to clear some cap room if theyre indeed going after Richards. just wanna hear your thoughts guys
